Detailed studies of sedimentology and petrology of oil ﬁelds, especially oil ﬁelds located in the seas, play a very important role in reducing the risk of danger, increasing harvest, and reducing the amount of environmental pollution. The South Pars gas ﬁeld in the waters of the Persian Gulf on the joint border line of Iran and Qatar and on the south coast of Iran has been used as a comprehensive model for this type of study. In these studies, the sedimentary environment and sequential stratigraphy of the Scorpion and Sarvak Formations in the South Pars gas ﬁeld in wells 1 and 3 have been investigated. Microscopic studies and analysis of gamma-ray and acoustic diagrams of these formations have led to the identiﬁcation of 9 facies in three facies belts related to wetland, dam, and open sea. Dam facies have been identiﬁed only in Sarvak formation. This study shows that the facies belts of the abovementioned formations in a ramp platform are also sloping. Sequence stratigraphy of Kazhdomi and Sarvak Formations in the study wells shows that Kazhdomi Formation has one sedimentary sequence (third category cycle) and Sarvak Formation has two sedimentary sequences. The lower boundaries of sequences 1 and 2 and the upper boundary of sequence 3 have type 1 (SB1) discontinuities, and the boundary between sequences 2 and 3 has type 2 (SB2) discontinuities.

“…First investigation in the Formation were reported by Bust and Mayo (Busk 1918) have named the Cretaceous-Eocene sequence as the Asmari Formation. Afterwards this Formation were studied by Richardson (1924), De Böckh et al (1929), Lees (1933), Zabihi Zoeram et al (2013), Aiello (2019), Monjezi et al (2019), that revised the age of Asmari Formation to the Oligocene-Miocene. This formation was defined regionally based on lithological and paleontological analysis (James and Wynd 1965;Adams and Bourgeois 1967;Motiei 1993;Aiello 2019;Hosseini Asgarabadi et al 2019;Sajadi and Rashidi 2019) and was deposited on a tropical platform, which covered southwestern Iran and parts of Iraq (James and Wynd 1965).…”

The present study deals with depositional environment and microfacies analysis of the Asmari Formation in the Nasr-Abad section of Zagros basin in SW of Iran. The thickness of 240 m with Nasr-Abad stratigraphic section to define microfauna is taken from Asmari Formation. Asmari Formation is located in SE of Shiraz. According to the identified index microfossils, following three Oligocene assemblages are determined: 1: Nummulites fichteli-Nummulites vascus, 2: Archaias asmaricuas-Archiaias hensoni, and 3: Peneroplis evolutus-Austroterillina howchini. According to the field observation, thin section studies and the results of petrographic analyses, four microfacies contain open marine (MF1-3), shoal (MF-4), lagoon (MF5-7) and tidal flat (MF8-9) depositional environments are identified. Based on the paleoenvironmental interpretations, the lack of barrier reefs as well as of gradual facies change, a homoclinal ramp mainly represented by its inner and middle sectors is proposed and reconstructed for depositional environment of the Asmari Formation in the studied section.
